They'll probably do it... But 99.9% chances it's going to be a 1-piece undyeable set, that only caters to the few wanting to Cosplay Alisaie.

Those Scion sets are such a wasted opportunity for them to get more sales. It's a given that they'd sell much more if the visible separate parts were actual different items and dyeable, but apparently the Mogstation team don't think it's worth the extra effort it takes. Heck, if they have to refit the clothes to every race out there, might as well go this extra length and have boots/shorts/jacket separated.

In fact, the few Scion sets I bought are actually the ones with separate items because I can mix and match them. Hard pass on everything else.
